EJECTOR FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 528,508, dated October30, 1894 Application tiled February 14, 1894. SerialNo. 500,109. (Nomodel.)

To @ZZ whom t may concern:

Be it known that we, RIMMON C. FAY and GEORGE E. HUMPHREYS, citizens ofth e United States, residing at Ilion, county of Herkimer, State of NewYork, have invented certain new and useful Improvements inDouble-Barreled Shotguns, of which the following is a specification.

The object of our invention is to produce a shot gun whose mechanismshall be more simple and positive in its action than those in commonuse, to increase the general efficiency and durability of the gun and tolessen the cost of production.

Our invention relates, broadly speaking, to a class of guns known asautomatic ejector, hammerless shot guns, operating on the break-downprinciple. We will first describe our improvements in detail withreference to the accompanying drawings and then point out in the claimsthe novel parts.

In said drawings: Figurel represents a longitudinal section of ourimproved gun showing the operating parts in a position of safety butcocked and ready to be discharged when the safety is thrown. Fig. 2represents a central longitudinal section of our improved gun showingthe safety thrown and the gun discharged. Fig. 3 is a centrallongitudinal section showing the barrels of the gun turning on thebreech joint. This view illustrates the gun during the preliminarymovement of the opening. Fig. 4 is a central longitudinal section of ourimproved gun showing the limit of the movement of the barrels upon theirpivot at the breech with one of the cartridge ejectors in its outwardand extreme position. Fig. 5 represents a cross section of our improvedgun on the line 5 5, Fig. 1. Fig. 6 is a rear end view of the fore-endremoved. Fig. 7 is a cross section on the line 7-7, Fig. 1. Fig. S is ahorizontal section showing certain of the main working parts. Figs. 9and 10 are detail views showing the closed and open positions of the toplever. j

In the longitudinal sectional views above referred to, it will beunderstood that the continuity of the sectional line is at times broken,said line being represented at 1-1, Fig. 8, for the purpose of bringingout some special feature at a particular point or points and thedrawings are to be read in this light. As far as possible the continuityof the section upon a constant line has been maintained.

The gun barrels 1 are connected to frame 2 by usual pivot bolt 3 andhave lugs 4 notched to engage a locking bolt 5 which is adapted to beoperated by a top-lever 6, top lever bolt 7 and crank arm 8. The hammers9 are pivoted at 10 and each is grooved at 11 to receive the down-turnedend of its main spring 12. The main spring is preferably not fixed tothe frame but is placed in a longitudinal groove 13 and its connectionto the hammer by the groove 11 is such that the action of cocking thehammer shifts the main spring longitudinally.

For each hammer we arrange upon the pivot bolt 3 al cocking lever 14whose rearwardly projecting arm engages beneath the forward arm of thehammer. The forward arm of the cocking lever is tapered as shown at 15and enters a correspondingly tapered recess orV hole 16 in the rearsurface of the fore-end 17. The holes 16 are made sufficiently largerthan the tapered ends of the cocking levers and are so tapered as topermit the ends of the cocking levers to enter them whatever theposition of the cocking lever so that the foreend may be taken off andreplaced whether the hammers be cocked or uncooked.

We design to have the ejector action of conjoint action when required sothat either or both of the shells can be ejected according to whetherone or both of the cartridges have been discharged.

1S is the divided ejector having an independently operating part foreach barrel. With the rear of each part engages an ejector hammer 19pivoted at 2O on the fore-end and engaged by the ejector-hammer spring2l.

22, 22 are the ejector hammer sears pivoted at 23 on the fore-end andhaving their forward arms adapted to engage a notch or shoulder on eachej ector hammer 19 and their rearward arms passing through a slot 24 inthe rear of the fore'end 17 and adapted to be engaged by the forward endof the main springs 12. Between the ejector hammer sears 22 and upon thesame pivot 23 we arrange the ejector hammer releasing scar 25 the twobarrels independent but capable of IOO which has its forward end hookedsomewhat farther from the pivot 23 than the hooks of the sears 22 andwhose rearward arm 2G projects through the rear of the fore-end inposition to engage a lug 27 on the frame when the gun is broken.

28 is athree-leaf spring. The leaves of each bear upon and operateindependently the several parts 22 and 25. The divisions between theleaves of the said spring are sufficiently extended to insure theindependent operation of its parts.

The extractor 18 is positively limited in its motion by means of an` arm29 fixed to the gun frame and entering a suitable slot or recess 30(shown in dotted lines) in the extractor.

In putting the gun together, the tapered forward end 15 of the cookinglevers 14 will, as already stated, readily enter the holes 16 in therear of the fore-end whatever the position of the cooking levers be. Ifthe gun be uncooked, the opening of the breech will cock it as thecooking lever will have its rear end lifted by the downward movement ofthe fore-end as shown in Fig. 4 so tilting back the hammer until it iscaught by the sear 31. This movement slides the main spring 12 to theposition shown in Fig. 4 and it retains this position when the gun isagain closed as in Fig. 1. In this position it does not engage the rearends of the extractor hammer sears 22 which accordingly are inengagement with the shoulder on the extractor hammer so that the gun canbe opened and closed without operating the ejector.

If now both barrels be discharged bringing the hammers to the positionshown in Fig. 2, the main springs are slid forward to engage and liftthe rear ends of the sears 22. The action of the ejector hammer springs21 therefore as the gun is opened causes the ejector hammers 19 to turnslightly until they are arrested by the engagement of their shoulderswith the hook of the releasing sear 25. This slight shifting of thehammers prevents their re-engagement by the sears 22 when the latter arereleased by the main springs 12 on opening the gun. The ejector hammersand their sears will now move with the fore-end around the pivot bolt orframe joint as the gun opens until the rear arm 26 of the releasing sear25 strikes the lug 27 on the frame, when the releasing scar is caused torelease both hammers and they suddenly project the ejector and eject theshells from the gun. If either of the barrels has not been dischargedand its hammer is still cocked, the corresponding main spring willremain in the position shown in Fig. 1 and the corresponding sear 22 inengagement with its ejector hammer 19 so that the ejector in that barrelwill not be operated when the gun is opened. When the gun is closed, theejector is pushed in by impinging on the face of the frame in customarymanner and in its action forces down the ejector hammers 19 in positionto be again engaged by the sears 22.

The barrels have a notched extension 32 engaging the shoulder of the toplever 6 as shown in Fig. 9. The top lever is grooved as shown in Fig. 10at 39 to permit the extension to pass up when the top lever is turned.

34 is a safety slide milled so as to be capable of easy operation by thethumb. It has two arms 35 projecting into the chamber of the stock 36 ofwhich arms the rear and longer one bears a pin 37 with which engages abumped spring 38.

39 is the safety-slide trigger-looking-lever bearing at its upper endbetween the arms 35 of the safety-slide, pivoted on asupporting arm 40on the trigger plate and provided at its lower end with a pin 41projecting on each side to engage the backs of triggers 42.

43 is the safety-slide bolt hinged to the lever 39 and guided by thebolt 44 in the plane of the barrel locking bolt 5. When the bolt 5 isretracted to unlock the barrels and the gun is opened, it strikessafety-slide bolt 43 and moves it in the same direction. This movementcausesI the trigger locking lever 39 to swing in its support and pushback the safety-slide until its pin 37 engages behind the hump of thespring 38. As soon as it has passed the highest part of the spring, thepressure of the spring completes the movement throwing forward the lowerpart of the lockinglever 39 so that the pin therein passes over andlocks the triggers.

The space between the bolt 5 and the bolt 43 is such that if when thegun is open, the slide 34 be pushed forward at the same time that bothtriggers are pulled, the safety piny 41 will slide from the triggers asthe gun is closed and the hammers may thus belet down gradually withoutfiring the cartridges.

The trigger spring usually engages in a round hole in the trigger sothat if the spring is long or short a portion of its power is consumedin a pulling or pushing action against the front or back side of thehole which impairs the delicacy of the trigger adjustment.

IIO

To obviate this trouble we form the hole 45 in the trigger whichreceives the end of trigger spring 46 oblong instead of round. This formallows a more delicate adjustment of the trigger spring and insures itspower being applied in the proper line of pressure.

Having thus described our invention, the following is what we claim asnew therein and desire to secure by Letters Patent:
